Growing Cilantro 101: Everything a Beginner Needs to Know
Q: How often should I water my indoor cactus?
A: Watering frequency for indoor cacti varies depending on the season and the specific type of cactus. Generally, you should water your cactus when the top inch of soil is dry to the touch. During the growing season (spring and summer), most cacti may require watering every 2-3 weeks. In the fall and winter, reduce watering to once a month or even less, as many cacti enter a dormant phase during this time.
Q: What type of soil is best for indoor cacti?
A: Cacti thrive in well-draining soil. A cactus mix or a blend of potting soil with sand, perlite, or pumice is ideal, as it allows excess water to escape and prevents root rot. Ensure that the pot you choose has drainage holes to facilitate proper drainage.
Q: Do cacti need direct sunlight?
A: Most cacti prefer bright, direct sunlight, especially during their growing season. However, some varieties, like the Christmas cactus and Easter cactus, thrive in bright, indirect light. It's essential to consider the specific needs of each cactus type to ensure they receive the right amount of light.
Q: Can indoor cacti survive in low humidity?
A: Yes, cacti are well-suited to low humidity environments, as they are adapted to arid conditions. However, some species, like the Christmas and Easter cacti, may benefit from slightly higher humidity levels, especially during their blooming seasons. For most other cacti, low humidity is not a concern.
Q: What temperatures do indoor cacti prefer?
A: Cacti generally prefer warm temperatures, typically ranging from 70°F to 90°F (21°C to 32°C) during the day. However, they can tolerate cooler temperatures at night, especially during the winter months. Avoid exposing them to frost or extreme cold, as this can damage or kill the plant.
Q: Are natural pest control methods effective?
A: Yes, natural pest control methods can be very effective when applied correctly. They often require more frequent application and monitoring than chemical pesticides, but they support long-term garden health.
Q: Can I use natural pest control methods in vegetable gardens?
A: Absolutely! Many natural pest control methods are safe and effective for vegetable gardens. They help protect your crops while promoting a healthy ecosystem.
Q: How do I know which pest control method to use?
A: Identifying the specific pests affecting your plants is the first step. Once you know the pest, you can choose the most appropriate natural control method from the list provided.
Q: Are natural pest control methods safe for pets and children?
A: Most natural pest control methods are safe for pets and children. However, it’s always a good idea to keep them away from treated areas until sprays have dried, especially with essential oils and soaps.
Q: How often should I apply natural pest control treatments?
A: The frequency of application depends on the specific method and the level of pest infestation. Monitor your garden regularly and reapply treatments as needed, especially after rain or watering.
Q: Can I grow potatoes vertically in a small space?
A: Yes, you can! Potatoes are perfect for vertical growing setups, like a potato tower or stacked garden. As the potato vines grow, you can keep adding layers of soil or mulch to encourage more tubers higher up. Vertical growing works well in smaller spaces and can even be done in a deep raised bed or large container. Just make sure to keep the vines supported if they start sprawling.
Q: What’s the difference between ‘earlies’ and ‘maincrop’ potatoes?
A: "Earlies" are potatoes that mature faster, usually within 70-90 days, and are perfect for harvesting as new potatoes. They’re smaller and tender with thin skins. "Maincrop" potatoes take longer to mature, about 100-120 days, and they’re usually larger with thicker skins, which makes them ideal for storage. If you want a long harvest, you can plant both types!
Q: How do I keep my potatoes from turning green?
A: Green potatoes occur when tubers are exposed to sunlight, which leads to the production of solanine, a bitter compound that’s toxic in large amounts. To avoid this, keep the soil mounded over the plants as they grow and ensure that no tubers are peeking out from the soil. Green potatoes should be discarded, as solanine doesn’t go away with cooking.

Discover the joys of growing cilantro indoors and enjoying its flavorful leaves in your culinary creations.
Required Materials for Growing Cilantro Indoors
Seeds (coriander seeds)
Cilantro is the leafy part of the coriander plant, and the seeds are what you'll plant to begin the growing process. Choose slow-bolting varieties for a longer harvest period. These can be purchased from garden centers, nurseries, or online suppliers.
Container (with drainage holes)
A container with adequate drainage is crucial to prevent root rot, a common issue with overwatering. Opt for a pot with drainage holes and a saucer underneath to collect excess water. A 6-8 inch pot is sufficient for a single plant.
Potting mix (well-draining, nutrient-rich)
Cilantro thrives in well-draining soil that retains moisture without becoming waterlogged. Choose a pre-mixed potting mix formulated for herbs or vegetables, as it contains the necessary nutrients for optimal growth.
Watering can or spray bottle
Consistent moisture is important for cilantro, but overwatering can have serious consequences. A watering can with a gentle rose attachment or a garden spray bottle allows for precise watering without disturbing the seeds or young seedlings.
Step-by-Step Guide to Growing Cilantro from Seed Indoors
- Seed Preparation:
- Crushing (Optional): While not mandatory, gently crushing the seeds with a mortar and pestle or the back of a spoon can help break down the outer hull and speed up germination.
- Soaking (Optional): Soaking the seeds in room temperature water for 8-12 hours before planting can further enhance germination rates.
- Planting:
- Container: Choose a pot with drainage holes and a saucer to catch excess water.
- Potting Mix: Fill the pot with a well-draining, nutrient-rich potting mix formulated for herbs or vegetables.
- Sowing: Sow the seeds about ¼ inch deep and 2-3 inches apart. Cover with a thin layer of soil and gently press down.
- Germination:
- Moisture: Keep the soil consistently moist but not waterlogged. Misting with a spray bottle can be helpful.
- Temperature: Cilantro seeds germinate best in cool temperatures, ideally between 50-70 degrees Fahrenheit (10-21 degrees Celsius).
- Timeline: Germination usually takes 7-14 days.
- Early Growth:
- Thinning: Once the seedlings have a few sets of true leaves, thin them out, leaving the strongest ones spaced 4-6 inches apart.
- Light: Provide bright, indirect sunlight for at least 6 hours a day. If natural light is limited, use a grow light.
- Ongoing Care:
- Light: Maintain the 6 hours of daily light exposure.
- Water: Water when the top inch of soil feels dry, ensuring good drainage to prevent root rot.
- Fertilizer: Feed every 2-3 weeks with a balanced, water-soluble fertilizer diluted to half strength.
- Soil: Monitor soil moisture and nutrient levels. Repot if the plant becomes rootbound.
- Temperature & Humidity: Keep temperatures between 50-80 degrees Fahrenheit (10-27 degrees Celsius). Cilantro prefers moderate humidity.
- Pests & Diseases: Watch for aphids or fungal diseases, and address them promptly.
- Pruning and Propagation:
- Pruning: Regularly harvest leaves to encourage bushier growth. Pinch off any flower buds to prolong the harvest.
- Propagation: You can take stem cuttings and root them in water to create new plants.
Harvesting Cilantro
When to Harvest:
- Early Harvesting: You can start snipping leaves as soon as your cilantro plant reaches about 6 inches tall.
- Optimal Flavor: The most flavorful leaves are young and tender. Harvest them before the plant starts to flower (bolt).
- Regular Harvesting: Frequent harvesting actually encourages bushier growth and delays bolting, giving you a longer harvest window.
How to Harvest:
- Choose Your Leaves: Select outer, mature leaves or stems. Avoid harvesting the tender inner growth, as this is where new leaves will develop.
- Cut or Pinch: You can use clean scissors or your fingers to harvest.
- Scissors: Snip stems about 1-2 inches above the soil line.
- Pinching: Pinch off individual leaves or small stems at their base.
- Harvest Amount: Don't take more than 1/3 of the plant at a time. This allows the cilantro to continue growing and producing new leaves.
- Frequency: Harvest regularly, every few days or weekly, depending on your needs and the growth rate of your plant.
Signs Your Cilantro is Ready to Bolt:
- Flower Buds: The appearance of small, white flower buds is a sign that your cilantro is about to bolt.
- Leggy Growth: The plant may become tall and spindly.
- Stronger Flavor: The leaves may develop a stronger, more pungent flavor.
Tips for Harvesting Bolting Cilantro:
- Collect Seeds: If your cilantro does bolt, let the flowers mature and collect the seeds (coriander). You can use these for cooking or save them for planting next season.
- Replant: Consider starting a new batch of cilantro from seed to ensure a continuous supply of fresh leaves.
Repotting Cilantro
When to Repot Cilantro:
- Rootbound: The most common reason to repot is if your cilantro becomes rootbound. This means the roots have filled the pot and are circling the bottom or pushing through the drainage holes.
- Slowed Growth: If you notice your cilantro's growth has slowed or stopped, even with proper care, it might be rootbound and in need of a larger pot container.
- Wilting: Frequent wilting, even after watering, can be a sign of rootboundness. The roots can no longer absorb enough moisture to support the plant.
Choosing a New Pot:
- Size: Select one that's 1-2 inches larger in diameter than the current one. This provides enough space for the roots to spread out without being excessive.
- Drainage: Ensure that it has drainage holes to prevent waterlogging.
- Material: Plastic, terracotta, or ceramic ones are all suitable for cilantro. Choose one that suits your aesthetic and budget.
How to Repot Cilantro:
- Prepare the New Pot: Fill it about 1/3 full with fresh, well-draining mix.
- Remove the Cilantro: Gently loosen the soil around the edges. Carefully turn it upside down, supporting the cilantro at the base, and slide it out.
- Inspect the Roots: Check for any damaged or rotting roots and trim them away with clean scissors. If the roots are severely entangled, gently loosen them with your fingers.
- Place in New Pot: Position the cilantro in the center, making sure the top of the root ball is level with the soil surface. Fill in the gaps around the root ball with mix, gently firming it down.
- Water Thoroughly: Water the repotted cilantro thoroughly, allowing excess water to drain away.
